Some weeks ago, Brad Keselowski was "secretly" fined for speaking out on the new fuel injection technology, letting the "cat out of the bag" that this is to be far from modern, effective and efficient technology, but rather more like early 1980's throttle body.
I can think of two VALID reasons why NASCAR would take this path, however, each points out a serious,serious issue that this governing body has to face, and so far has failed to adequately address.
NASCAR has not moved forward on technology issues because it has little or no knowledge on how to monitor and police the new "opportunities" it will present the crews to be creative. It is moving much slower than the industry, instead of leading development of innovations. For the manufacturers, this is a serious issue, as racing budgets could at one time be partially justified as funding product development. I do not propose that NASCAR become the technological equivalent of F1 racing, but in many regards, "amateur" leagues like SCCA are more advanced, as the utilize many of the street legal innovations. NASCAR needs to find and hire someone who can guide their technological advancement, and fast.
NASCAR may be purposely holding back on new technology as it has yet to be able to govern a way to level the playing field for all teams. Any new major technology will add significant expense for teams to implement, and the superteams will come up with that funding first and biggest, thus widening the already significant gap between themselves and the second and third tier teams. Look at the sponsor issue with Bower this year: MWR offered up to field the team for a much lower price tag than RCR. Racing s now about horsepower per dollar.
I'm looking forward to the Grand Am series more and more.
